Method of controlling transmit power of ue in wireless communication system and apparatus for the same

Abstract

Disclosed herein is a method of transmitting a signal at a user equipment (UE) in a wireless communication system. The method includes receiving a radio resource control (RRC) configuration message from a network; determining a preference value relating to power saving after receiving the RRC configuration message; and transmitting the determined preference value relating to the power saving to the network.

         21 . A method of receiving a signal at a network in a wireless communication system, the method comprising:
 transmitting a radio resource control (RRC) configuration message to a user equipment (UE), wherein the RRC configuration message comprises a first field that enables the UE to transmit to the network a preference value relating to power saving; and   receiving a first preference value relating to the power saving from the UE,   wherein the received first preference value relating to the power saving is different from a second preference value relating to the power saving which was received last from the UE.   
     
     
         22 . The method of  claim 21 , wherein the RRC configuration message is a RRC configuration enquiry message or a RRC reconfiguration message. 
     
     
         23 . The method of  claim 21 , wherein the first preference value relating to the power saving is received using a RRC reconfiguration complete message or a RRC configuration response message. 
     
     
         24 . The method of  claim 22 , wherein the first preference value relating to the power saving is included in a second field of a response message of the RRC reconfiguration message. 
     
     
         25 . The method of  claim 24 , wherein the second field is a reason field. 
     
     
         26 . The method of  claim 21 , wherein the first preference value relating to the power saving is based on an application which is being driven in the UE. 
     
     
         27 . A communication apparatus comprising:
 a radio frequency (RF) module configured to perform a function for converting a base band signal into a radio signal or converting the radio signal into the baseband signal;   a processor controls the RF module to:   transmit a radio resource control (RRC) configuration message to a user equipment (UE), wherein the RRC configuration message comprises a first field that enables the UE to transmit to the network a preference value relating to power saving, and   receive a first preference value relating to the power saving from the UE,   wherein the received first preference value relating to the power saving is different from a second preference value relating to the power saving which was received last from the UE.   
     
     
         28 . The communication apparatus of  claim 27 , wherein the RRC configuration message is a RRC configuration enquiry message or a RRC reconfiguration message. 
     
     
         29 . The communication apparatus of  claim 27 , wherein the first preference value relating to the power saving is received using a RRC reconfiguration complete message or a RRC configuration response message. 
     
     
         30 . The communication apparatus of  claim 28 , wherein the first preference value relating to the power saving is included in a second field of a response message of the RRC reconfiguration message. 
     
     
         31 . The communication apparatus of  claim 30 , wherein the second field is a reason field. 
     
     
         32 . The communication apparatus of  claim 27 , wherein the first preference value relating to the power saving is based on an application which is being driven in the UE. 
     
     
         33 . A communication apparatus comprising:
 a radio frequency (RF) module configured to perform a function for converting a base band signal into a radio signal or converting the radio signal into the baseband signal;   a processor controls the RF module to:   receive a radio resource control (RRC) configuration message from a network, wherein the RRC configuration message comprises a first field that enables the UE to transmit to the network a preference value relating to power saving,   determine a first preference value relating to the power saving after receiving the RRC configuration message, and   transmit the determined first preference value relating to the power saving to the network when the determined first preference value relating to the power saving is different from a second preference value relating to the power saving which was last transmitted to the network.   
     
     
         34 . The communication apparatus of  claim 33 , wherein the RRC configuration message is a RRC configuration enquiry message or a RRC reconfiguration message. 
     
     
         35 . The communication apparatus of  claim 33 , wherein the first preference value relating to the power saving is transmitted using a RRC reconfiguration complete message or a RRC configuration response message. 
     
     
         36 . The communication apparatus of  claim 34 , wherein the determined first preference value relating to the power saving is included in a second field of a response message of the RRC reconfiguration message. 
     
     
         37 . The communication apparatus of  claim 34 , wherein the second field is a reason field. 
     
     
         38 . The communication apparatus of  claim 33 , wherein the UE is in a RRC connected mode. 
     
     
         39 . The communication apparatus of  claim 33 , wherein the first preference value relating to the power saving is based on an application which is being driven in the UE.
